Early life, education and family

Blake Gates Masters grew up in Tucson, Arizona. He attended Stanford University and Stanford Law School. In 2012 he married Catherine, whom he had known since high school. Arizona's public elections agency published a 2022 candidate biography identifying their three sons as Miles, Graham and Rex. This is a dated public candidate biography rather than an assertion about the family's present household.^[1]

Technology, investment and Peter Thiel

Masters co-founded Judicata, a legal-technology company, in 2012. He co-authored Zero to One (2014) with Peter Thiel. Masters was president of the Thiel Foundation from 2015 to 2022 and chief operating officer of Thiel Capital from 2018 to 2022. These separately organized entities shared a professional relationship with Masters; they should not be collapsed into a single company.^[2]^[3]

Electoral campaigns and support

Masters was the Republican nominee for the U.S. Senate in Arizona in 2022 and lost to incumbent Mark Kelly. He later ran for the Republican nomination in Arizona's 8th Congressional District in 2024 and lost the primary to Abraham Hamadeh.^[4]

During the 2022 Senate race, Thiel contributed substantial money to independent political spending intended to support Masters. The outside spending is separate from Masters' campaign committee receipts and separate from their documented employer–employee relationship.^[5]

Rockbridge Network

In August 2024, Reuters identified Masters among members or backers of the Rockbridge Network, a politically active donor network co-founded by JD Vance and Chris Buskirk. That reporting establishes a reported network association, not a claim that Masters founded Rockbridge, controlled its finances or coordinated every activity by its members.^[6]

Public-company board appointments

Masters has served on the board of PSQ Holdings, the company behind PublicSquare, since July 2023. A company annual report states he became lead independent director in January 2026. Separately, a 2026 SEC proxy filing identifies him as a director of GrabAGun Digital Holdings since July 2025. Both are documented corporate board roles, distinct from his earlier employment at Thiel Capital.^[3]^[7]^[8]
